.. specification of `Letters Patent i Pfntd May 17, 1921,

Application led March 25, 1920. Serial No.' 368,640.

To all whom t may concer/n.:

Be it known that I, HARRY E. Donna, a citizen of the United States,residing at St.r Louis, and State of Missouri, have invented certain newandA useful Improvements in Side Frames, of which the following'is aspecification. This invention relates to side, frames, and particularlyto side4 ,frames of the pedestal t e. f

y eretofore pedestal ltruck side frames have required a special journalbox. Accordingly, such a side frame could not be used for replacementsof arch bars or the standard type of frame, both of which useaster-QarBuilders j'ournal boxes. Therefore, one objectof this invention is toprovide a simple and novel pedestal truck side frame which willaccommodate Master Car Builders journal boxes in such a mane ner thatparts of the side frame and journal boxes will coperate to preventaccidentally relative lateral movement.

Another object is to provide a truck side frame which may be detachablyconnected to a journal box in a manner to obviate the use of bolts andwhereby an emergency fastening is formed should the truck be derailed orlifted from the track by any other part than the axles.

These and other objects are accomplished by means of the arrangementdisclosed in the accompanying sheet of drawings, in which- Figure 1 is afragmentary side elevation of a truck side frame embodying my invention, and shown in normal coperative position with a Master Car Buildersstandard .journal box;

' Fig. 2 is a fragmentary top the same arrangement an Fig. 3 is an endelevationof the same parts.

The various novel features of my inven- 4plan view of tion will beapparent from. the following description and the drawings, and, will'beparticularly pointed out. in the appended .'claims.

Referring to the gures of the drawings,

it will be noted that I have provided a truck -These extending jawportions 12 engage the side frame 10 having pedestal jaws 11, the lowerends of which terminate in laterallyr extending portions 12, which'extend toward each other lengthwise .of the side frame.

" provided my side frame sides of the Master Car Builders journal box 13intermediate its ends and more par-l ticularly intermediate the verticalplanes of the bolt lugs 14. vAs 1s apparent from the arrangementdisclosed in the igures of the.

drawings, it would be impossible to apply the side frame to the journalbox by a relative vertical movement'while the jaw extensions 12 arevintermediate the journal box bolt lugs 14. Accordingly, to apply theside frame tothe journal box when the latter is fixed on the journal,the side frame 10 is moved inwardly with respect to the journal box to apoint where the relatively narrow jaw extensions l2 may pass verticallydownwardly between the inner journal box bolt lugs v14 and thedust-guard housing 15.

With the side frame in this position, the

same may e lowered, permitting the' jaw extenslons 12 to pass verticallydownwardly beyond the upper journal box bolt lugs 14,

whereupon fthe side frame may be moved vrelatively outwardly withrespect to the journal boxv to take its normal loperating position. Q,f.

It will be noted that the side frame 10 is -provided with four housinglugs 16 which fit over the outside and embrace the four upper journalbox bolt lugs 14.' lTAccordingly, when the ljournal box 13 and sideframe have been moved relatively laterally to a point where the housinglugs 16 may assume the proper position with respect to the box lugs 14,the side frame 10A-is lo'wered into the position shown in Fig. 1 of thedrawings to prevent relative lateral move-y vare provided withralsed'portions 17 forming side shoulders or bearings 18. Ihave withoppositely arranged langles 19which are intermediate and connect t e lu16 and which engage or embrace the'si es vof .the shoulders or bearings18 of the journal box to assist in resisting the action on curves andalso on nient between the side frame and journal roughnor Auneven track.Not only will the flanges 19 assist the lugs 16 in overcoming relativelateral movement between the journal box and the side frame, but theflanges 19 will strengthen the lugs and provide a more durablevarrangement to overcome the severe service condltions.

It will be noted that the jaw extensions 12 are spaced from the housinglugs 16 vertically an amount to accommodate the box lugs 14 in applyingthe frame to and withdrawing the same from the journal box The pedestaljaw extensions 12 act as an emergency fastening for` maintaining theconnection between the side frame and the journal box, and therefore thewheels and axles, in the event that the truck is derailed or is liftedfrom the track by any other part than the axles. No bolts or otherfastenings -of any kind are used to hold the side frame in properposition other than the parts hereinabove specifically set forth; thehousing lugs 16 embracing the sides of the journal box lugs 14, theflanges 19 embracing the journal box bearings 18, and the pedestal jawextensions 12 bearing against the sides of the box for holding the samein proper relation to the side frame.. It will be understood that whenit is desired to replacel a broken journal box, the same may be done byraising the side frame an amount to properly accommodate the upperjournal box lugs 14 between the jaw extensions-12 and the housing lugs16, whereupon the new journal box may be moved laterally inwardly to thepoint where the housing lugs 16 may move ldown over the journal box lugs14 and the flanges 19 over the bearing portions 18.

It is my intention to cover all modications of the invention fallingwithin the spirit and scope of the following claims.

I claim:

1. A pedestal truck side frame, including pedestal jawshavinportionspwhich embrace' bolt lugs of aster Car Builders journalboxes, and having associated portions connecting said other portionslongitudinally and embracing bearings on said journal boxes normally, toprevent relative lateral movement between the I side frame and journalbox. v

2. A truck side frame, including pedestal .jaws havingV portions whichengage bolt lugs on Master Car Builders journal boxes, and havingstrengthening flanges connecting said portions which engage shoulderbearings on said journal boxes normally to prevent lateral movementbetween the side frame and journal box.

s 3. A pedestal truck side frame, including edestal jaws which embracebolt lugs on aster Car Builders journal boxes, and

having means intermediate said portions which embrace side shoulderbearings on said journal boxes normally to prevent relative lateralmovement between the side frame and journalbox, said pedestal jaws alsohaving portions which embrace the sides of the journal `box between thebolt lugs thereof for assisting .in maintaining the operative positionof said side frame and said journal box. I

4. A pedestal truck side frame having a plurality of lugs for embracingadjacent bolt lugs on Master Car Builders journal boxes, and havinflanges intermediate certain of said lugs igor embracing the shoulderportions on said journal boxes to prevent relative movement between thejournal box and side frame.

5. A pedestal truck side frame having four lugs for embracing adjacentlyarranged bolt lugs of the journal box, and having two Hanges connectingcertain of said four lugs for embracing shoulders on Athe journal boxnormally to prevent relative lateral movement between said side frameand journal box.

Signed at St. Louis, Missouri, this 20th day of March, 1920.
